A track device e.g a retainer for a track sliding aide comprises a first track 10, a second track 20, slidably received in the first track, a slide-aiding member 30 mounted between the first and second tracks and a retaining member 40 having a resilient hook rod 42 mounted to a front end of the first track. When the second track is removed from the first track, the resilient hook rod of the retaining member engages with an engaging notch 31 in a front end of the slide-aiding member, thereby retaining the slide-aiding member in place. When the second track is reinserted into the slide-aiding member and the first track, an unlatching member 50 on the second track urges the resilient hook rod of the retaining member to disengage from the engaging notch of the slide-aiding member, allowing the second track to move inward into the first track. |
